Rewinding Machine common fault - The coil does not run or is broken
1. Winding tension controller is not open - Open winding tension controller switch
2, the speed of the governor is too low - increase the speed of the governor
3, did not press the reset button - press the reset button on the two tension controllers
4, the tension tension controller tension is too small - increase the winding tension controller output current
5, unwinding tension control tension is too large - reduce the unwinding tension controller output current
6, the running button is damaged - replace the run button
7, tension controller failure - contact the manufacturer
8, governor failure - contact the manufacturer
Four release and one rewinding machine operation program ---
6. Check if the power indicator on the outside of the tension control cabinet is lit.
7. In the touch screen, you need to input or rewrite the following parameters:
1 counting length is cleared (if it is necessary to re-measure the length);
2 automatic acceleration speed (refers to the speed we reach after the automatic acceleration of the machine after pressing the acceleration button delay)
3 Automatic acceleration time (refers to the time required for the machine to automatically accelerate from zero speed to the design of the highest machine speed. The shorter the time setting, the faster the acceleration.)
8. Tension control: Set the tension of each discharge motor in the touch screen. The discharge motor mainly provides a reverse torque, generates tension on the paper surface, keeps the paper web flat, and the speed control of the discharge motor is a process of gradually increasing speed, but the line speed remains unchanged.
9. Each console has its own power switch, which can be switched on and off as needed.
10. The forward and reverse running buttons are set on the console, and the user can select the running direction according to the needs.
Rewinder mechanical structure and control process ---
Third, the rewinding machine control performance indicators
The rewinder is the last process in the papermaking process. The performance of the rewinder determines the quality of the finished paper roll. A complete rewinder must have the following properties:
1. Adjusting mechanism of pressure of the platen roller
As the rewinder continuously performs rewinding, the diameter of the finished paper roll is gradually increased, and the weight of the finished paper roll is also gradually increasing, so that the contact points of the finished paper roll with the front and rear bottom rolls are also changing. So you can come to a conclusion like this:
If the pressure of the platen roller is kept constant and does not change, the pressure between the contact points of the finished paper roll and the front and rear bottom rolls is not guaranteed to be constant, and the change in the contact point causes the pressure generated between them to change accordingly. Therefore, if we want the paper roll to reach the best form, we must adjust the pressure exerted by the platen roller to compensate for the influence of the above two factors. Only in this way can the pressure between the front and rear bottom rollers and the finished paper roll be guaranteed. Variety.
2, support roller torque program control In the rewinding process of the finished paper roll, in order to obtain high quality finished paper roll, the speed control or the support roller torque should meet certain conditions, if the speed control is used, the support roller The speed between the two should be less than 0.2%. As the diameter of the paper roll increases, the speed of the two supporting rollers must be close. Only in this way can the high quality finished paper roll be rewinded, but some quick checking systems cannot consider this design.
